Speeding page load time is a prime target for most developers. This tool provides performance reports that analyze every visited page based on known best practices from Google, Yahoo! and dynaTrace. AJAX Edition reports performance data that finds problematic JavaScript code affecting page load times. This utility will provide you clues to browser caching, network round-trip delays and server-side request times. These are the kind of parameters you will need to optimize to manage consistent fast page load times. The interface has suitable graphics that help developers. This is no tool for the novice but for hard core developers. It is a nice tool overall.
